{"id":"CVE-2026-118758","published":"2026-10-29T17:18:06.487","lastModified":"2026-10-29T21:17:16.737","description":"Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.18.0, the volume artifact handler for GET /artifacts/get?source=volume did not confine a caller-supplied file path to the selected volume. A caller who can reach the route and identify an existing mounted volume can use path traversal to read files outside that volume when the artifact-serving process can read them. The frontend pod serves the request when artifact proxying is disabled, while the selected namespace's artifact-service pod serves it when proxying is enabled. A deployment with authentication disabled requires no application credentials; in multi-user deployments, the caller ordinarily must be authorized for the supplied namespace. This issue is fixed in version 2.18.0.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kubeflow/pipelines/blob/2.18.0/docs/operator-guides/upgrade-2.18.md#custom-storage-configuration-and-rollout","tags":[]},{"url":"https://github.com/kubeflow/pipelines/commit/4d9bc5ab12b67efedb3923ef428a399cb445cf5f","tags":[]},{"url":"https://github.com/kubeflow/pipelines/pull/13677","tags":[]},{"url":"https://github.com/kubeflow/pipelines/releases/tag/2.18.0","tags":[]},{"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-2fg9-fx2f-439r","tags":[]}],"exploitRefs":[{"url":"https://github.com/kubeflow/pipelines/blob/2.18.0/docs/operator-guides/upgrade-2.18.md#custom-storage-configuration-and-rollout","tags":[]},{"url":"https://github.com/kubeflow/pipelines/commit/4d9bc5ab12b67efedb3923ef428a399cb445cf5f","tags":[]},{"url":"https://github.com/kubeflow/pipelines/pull/13677","tags":[]},{"url":"https://github.com/kubeflow/pipelines/releases/tag/2.18.0","tags":[]},{"url":"https://github.com/kubeflow/pipelines/security/advisories/GHSA-2fg9-fx2f-439r","tags":[]}],"hasPoc":true,"ai":null}
